Abstract: 27,630. Imray, O., [Monoline Composing Co.]. Nov. 24. Linotype and like machines.-Relates to improvements in the 'Monoline' machine described in Specification No. 17,135, A.D. 1893. The matrix bars and spacers are essentially the same as those used in the former machine. Fig. 2 shows a side elevation, and Fig. 36 a part front elevation, of a machine embodying the improvements. Magazine and matrix bar delivering mechanism. The magazine, which is similar to that in the former machine, has the front ends of its delivery channels covered by a hinged transparent door 12<a>, held closed by a latch bar which works automatically when the door is swung to. The front matrix bar in each channel is supported by the end of a horizontal delivery slide 13, and when a slide is withdrawn the bar falls into the assembly box. The slides 13 are held by pawls 17 operated to release the slides by levers connected by rods to the slides 20<a> actuated by the finger keys. When released, the slides 13 are rapidly moved rearwardly to deliver a matrix bar by springs 16, and are re-set by an oscillator 23. On each slide 13 is a finger which feeds the matrices along the delivery channels of the magazine. The oscillator 23 carries a cam 26, having a roughened or serrated surface, which normally stands just clear of a roughened continuously-rotating roller on the shaft 271. When a slide 13 moves rearwardly it causes the oscillator to move until the cam engages with the roller, and the oscillator is then swung forward to re-set the slide. Each slide is engaged by the arm 30 of one of a series of angle levers pivoted on to the oscillator. When the oscillator springs back to position, it engages a pivoted stopping-dog by which it is held until the operated slide 13 disengages the stopping-dog. When the cam disengages the roller, it is stopped in position by a spring engaging a flattened portion of the shaft. The oscillator is connected by a rod 38 to an arm on a shaft carrying vibrators 40, one for each magazine chamber. Space-bar lever and feeder. The end space bar is lifted by a slide 51, and is then moved laterally into the delivery channel, and pushed down it by the slide 51. The latter is connected to a lever 41, the vertical arm of which is held by a dog in such position that the slide 51 is raised. The dog is operated to release the lever by the space key 50 &c., and the slide is then moved down by a spring. The lever is returned and re-engaged with the dog by the oscillator 23 at the next operation of a key. Assembly box, ejector devices, and line carriage. The matrix bars as they descend into the assembly box are stopped with the proper character in line, by stop bars 56<a> moved by the slides 20<a>, and the stop bars are re-set by a slide 57 connected by a rod 58 to the lower end of the oscillator. Each matrix is guided into the assembly box 61 by a guide 59<a>, and is pushed out into the raceway, by an ejector finger, which also opens out spring jaws forming the box 61. The motion of the jaws is limited by a yoke 66, which contains springs for closing them. The ejector is operated from the oscillator. The matrices are pushed past a retaining-pawl which prevents them from moving backward, and the line is formed between this and the yielding line abutment. The line abutment consists of fingers projecting through slots into the raceway. The fingers are pivoted on to a sliding block and held in operative position by a locking-pawl. The sliding block is connected to an arm which is moved against the pressure of a spring as the line is formed. When the composed line of matrices is carried along to the left, by the line carriage, the line abutment is carried along until the locking-dog is engaged by a fixed stop and releases the fingers, which are then withdrawn from the raceway, and the slide is returned by the spring arm. The latter carries a bell hammer which sounds an alarm when the line is nearly completed. The line carrier 60 is similar to that of the former machine, and is moved along the bar 89 by the lever 90 operated by a cam on the main line shaft 92. The lever 90 is jointed at 94, and the two parts held in position by a spring so that it may yield when the line carriage is stopped in the anvil. The wing 96, between which and a lug 108 the line is held, swings on the guide-rod 97 and is locked in position to engage the line by a spring bolt 98. The bolt 98 is operated to unlock the wing 96 by a lever which engages projections as the carriage returns to normal position. The lug 108 is moved to release the line after a cast, by the operation of a slide 112 on the carriage 60. On the slide 112 is a pin 114 operated by a sliding bar 116 pivoted to an arm on the auxiliary shaft, which is rocked by means of a cam on the main shaft &c. After this preliminary release at the casting point the matrix bars are pushed down until their lower ends are at one level and the spacers are retracted. The line is again released at the distributer by means of a pivoted dog 126 which engages a roller 128 on the slide 112 as the carriage moves back. The primary matrix depresser 117 is on a vertical slide 129 connected by a rod 130 to a lever 131 connected to an arm on the auxiliary shaft. The movable aligning-bar in the anvil 136 is retracted by an eccentric pin on a shaft 137 having an arm 137<a> connected with the auxiliary shaft. A secondary or safety matrix depresser 159 is provided, and is placed on the mould frame 160 by which it is moved into position to engage the matrices as they move to the distributer. The justifier, substantially the same as before, comprises a shoe 139 on the slide 140 connected by a spring link 145, Fig. 2, to a lever 146 operated by a cam 147 on the main shaft. The matrices are held down during justification by a braced flange on the fixed aligning bar. Casting-pot, mould, and mould frame. To prevent undue heating of the metal in the well of the pot, the base of the well is raised above the bottom of the pot, leaving a space for molten metal between the two. The pot is adjustably suspended in its surrounding jacket, and the latter is supported in roller bearings to facilitate its sliding motion. The pot is moved by a cam which moves the pot and mould up to the matrix line (pressing the latter against the anvil 136) for the cast, and subsequently moves the pot and mould frame forward to bring the safety depresser 159 into operative position. The roller on which the cam acts is in roller bearings, and is adjustable. The mould frame 160 is pivoted at one end 160<a>, and is moved to and fro by direct connections with the metal pot, and its movement is steadied by a guide-notch engaging a fixed guide-flange 160<b>. The mould slides in the frame 160, and after the cast it is moved opposite the ejector blade by which the type-bar is ejected between the trimming-knives 169. On the frame 160 is a knife for trimming the foot of the type-bar. The mould is moved by a lever operated by a cam on the main shaft. The trimming-knives are cleared as the mould moves to the ejector by a wiper 182 on a slide 178 on the mould frame. The galley consists of a box 191 removably held in position on the shaft 192 by a spring pin 194. As the type-bars fall they are pushed along the galley by a finger 199 on a shaft 198 having an arm operated by a tappet dog 201 pivoted on the sliding mould. Distributer. The levers 205 carrying the distributing-wires are operated by a vertical slide connected at 210 to a spring link 211 connected to a lever 212 operated by a cam on the shaft 92. The levers engage slots in the slide 210 by which they are swung, and the slots are so formed that, as the wires rise with the matrix bars, the wires have a certain amount of play or loose motion relatively to one another, to prevent them from gripping or pressing upon the distributing-hooks of the matrices. The matrices are thereby prevented from swinging unduly, and come to rest in proper position to be pushed into the compartments of the magazine. The pusher plate is carried by two sliding bars operated by a lever and cam on the main shaft ; and the upper edge of the plate is notched, forming fingers which move along the sides of the distributing-wires. Re-casting mechanism is provided whereby any number of type-bars can be cast from the same line of matrices. To accomplish this, the motions of the justifier, line carriage, distributer, primary depresser, and movable aligning bar &c. are discontinued while the casting and trimming &c. mechanism continue in operation. The cams operating these parts are mounted on a sleeve on the main shaft. In the sleeve is a sliding bar which is normally held in engagement with a fixed collar on the shaft, and the sleeve rotates with the shaft. The bar may be moved to disengage and stop the sleeve by a lever connected to a rod in reach of the operator. Pot cut-off and loose line signals. On the justifying-slide 140 is an adjustable cam arm 239. When a line of matrices is loose or of insufficient length to be expanded by the space bars, the slide 140 will unduly rise, and the arm 239 will come into contact with a bell-crank lever 242 pivoted at 244. The arm 245 of this lever engages a trip pawl 246 which operates an alarm bell. On the shaft 244 is an arm connected to a cut-off plate pivoted to the mould frame, which plate closes the mouth of the mould when the line is loose. Starting and stopping mechanism. The shaft 271 operating the oscillator is driven by a pulley 272 which may be engaged with or disengaged from the shaft by a handle knob 275. The shaft 271 is thus driven independently of the main shaft 92. The main shaft is driven by a pulley 276 geared to a wheel 278 on a tubular shaft, on which is loosely mounted a wheel geared to the line shaft 92. This wheel is clutched to the tubular shaft by a clutch operated by the shaft 283, the end of which bears against the clutch-operating lever. On the latter is an abutment adapted to be en
